      We reproduce the phenomenon of chemotaxis through a hybrid random walk model in two dimensions on a lattice. The dynamics of the chemoattractant is modelled using a partial differential equation, which reproduces its ...

      Article
      Accés restringit per política de l'editorial
      We study the effects of animal social networks with a weighted pattern of interactions on the flocking transition exhibited by models of self-organized collective motion. We consider variations of traditional models of ...
    • Modeling explosive opinion depolarization in interdependent topics 

      Ojer Ferrer, Jaume; Starnini, Michele; Pastor Satorras, Romualdo (American Institute of Physics (AIP), 2023-05-17)
      Article
      Accés obert
      Understanding the dynamics of opinion depolarization is pivotal to reducing the political divide in our society. We propose an opinion dynamics model, which we name the social compass model, for interdependent topics ...
